Answer:

it's very simple D

if you throw -ve sign to g(x) sign will change

and do simple calculation

Answer:

To find the difference between the two functions, we can subtract g(x) from f(x):

f(x) - g(x) = (5x² - 2x + 7) - (2x² + 6x + 3)

= 5x² - 2x + 7 - 2x² - 6x - 3

= 3x² - 8x + 4

Therefore, the difference between the two functions is f(x) - g(x) = 3x² - 8x + 4, which is answer D.

Step-by-step explanation:

calculate the slope m of the line using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 3 ) and (x₂, y₂ ) = (- 9, 6 )

m = [tex]\frac{6-(-3)}{-9-4}[/tex] = [tex]\frac{6+3}{-13}[/tex] = - [tex]\frac{9}{13}[/tex]

• Parallel lines have equal slopes.

Thus slope of a parallel line is m = - [tex]\frac{9}{13}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{9}{13} }[/tex] = [tex]\frac{13}{9}[/tex]

The solution the system of equations y = x – 15 and y = –2x + 3 is (6, -9)

An equation shows the relationship between numbers and variables in an expression.

Given the system of equations:

y = x – 15    (1) and

y = –2x + 3   (2)

From equation 1, substitute y = x - 15 into equation 2 using substitution method:

x - 15 = -2x + 3

x + 2x = 3 + 15

3x = 18

x = 6

substitute x = 6 in equation 1:

y = 6 - 15 = -9

y = -9

Answer:

a) $720.00

b) $882.00

Step-by-step explanation:

For part a) Shawna works 40 hours at $18.00 per hour.

Multiply to find the amount of money she made that week.

40 hrs × $18/hr

= 40 × 18

= 720

Shawna made $720.00

For part b) we can use the answer for part a, but she worked 6 hours more beyond the fulltime 40 hours. The 6 additional hours should be paid as overtime.

Her regular rate is $18/hr. Her overtime rate is "time-and-a-half" Multiply to find that pay rate.

18 × 1.5

= 27

For overtime, Shawna will earn $27/hour.

SO now part b)

She worked 46 hours.

40 × 18 = 720 and

6 × 27 = 162

Regular pay + overtime

= 720 + 162

= 882

Shawna will earn $882.00

The 4 basic types of lines are  Curved Lines, Straight Lines, Horizontal Lines, and  Vertical Lines.

How do lines work?

A straight group of points that stretch in opposing directions is what is known as a line.

the 4 basic types of lines are:

a) Curved Lines: A curved line is any line that is not straight. A curve results from a point that is not moving in a straight line.

b) Straight Lines: A straight line is the shortest path between any two points. We obtain a straight line if a point moves only in that direction.

c) Horizontal Lines: A horizontal line is any straight line that extends from left to right. Vertical lines are perpendicular to the y-axis and parallel to the x-axis.

d) Vertical Lines: From top to bottom or bottom to up, vertical lines are straight up and down. A vertical line is perpendicular to the x-axis and parallel to the y-axis.

The equations that could be used to find the price of one tire patch is given as follows:

The price for each tire patch is constant, meaning that a linear function is used to model the situation.

He initially had $22.20, and then for each tire purchased, his amount decays by the slope, hence the function that models the situation is given as follows:

f(t) = 22.2 - tx.

In which t is the number of tires purchased.

He purchased 4 tires, hence:

f(4) = 22.2 - 4x.

After the purchase, he had $1.90 remaining, hence:

1.9 = 22.2 - 4x.

The activity that burns calories at a faster rate is; Basketball

The general equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

We are given the equation;

y = 11x that represents the calories Jamila burns when cross-country skiing, where x is time in minutes and y is number of calories

Thus, the rate at which calories are burned is 11 calories per minutes.

In hours, this is; 60 * 11 = 660 calories per hour

From the graph, we see that the rate at which calories are burned = 1500 calories for every 2 hours. Thus;

We will find the parallel line:

y = (2/3)*x - 11/3

And the perpendicular line:

y = (-3/2)*x + 5

Here we start with the linear equation, we will get:

2x - 3y = 9

We can rewrite it to get:

-3y = 9 - 2x

y = 9/-3  - 2x/-3

y = -3 + (2/3)x

Remember that two lines are parallel if the lines have the same slope, so the equation of the parallel line will be something like:

y = (2/3)*x + b

And this line must pass through (4, -1), replacing these values we will get:

-1 = (2/3)*4 + b

-1 = 8/3 + b

-1 - 8/3 = b

-3/3 - 8/3 = b

-11/3 = b

So the linear equation parallel is:

y = (2/3)*x - 11/3

Now let's find the perpendicular line. Remember that two lines are perpendicular if the product between the slopes is equal to -1, then if the slope of the perpendicular line is m, we need to solve:

m*(2/3) = -1

m = -3/2

Then the perpendicular line is something like:

y = (-3/2)*x + b

To find te value of b, we need to replace the values of the point (4, -1) there, we will get:

-1 = (-3/2)*4 + b

-1 = -6 + b

-1 + 6 = b

5 = b

So the perpendicular line is:

y = (-3/2)*x + 5

A function is a rule or mapping that relates a set of inputs to a set of outputs. It is a mathematical expression that takes one or more inputs and produces a corresponding output. Functions are essential for solving problems in mathematics, science, engineering, and computing. They can be used to describe relationships, simplify calculations, and to create models that enable us to understand the behavior of complex systems.

This recursive function states that each successive term in the sequence is three less than the previous term. Therefore, the sequence will continue to decrease by three each time. For example, the sixth term would be -11 (a 5 -3) and the tenth term would be -21 (a 9 -3).

Expressing large numbers in terms of powers is known as an exponent. Therefore, the exponent describes the number of times a number has been multiplied by itself.

Exponentiation is a mathematical operation that involves the base number (b) and the exponent (or power) number (n), and is written as bn. Its pronunciation is "b (raised) to the (power of) n." Exponentiation corresponds to base multiplication when n is a positive integer; therefore, bn is the result of multiplying n bases:

In this case, it should be noted that x ^7/3 will simply be the cube root of x raised to power 7. This is illustrated as x ^7/3.
